    Trophy icon Small Arduino and NRF24L01 project 6 days left

    Main idea. To have multiple buttons around a office/home and when someone presses it a blink/signal will occur on the units like a common signal for an event. To ACK the signal everyone will need to press the button to confirm. This is a MVP concept design and I will add more functionality later. The only HMI will be a button and a LED (maybe RGB) so all info will be via that interface I will do all HW myself and want a fully functional software delivered. Assume the freelancer have this stuff at home to laborate and test the HW setup for a secure and proper debugging.

    Hi We can discuss any details over chat. The project consists of arduino and proteus .I need a temperature regulator for a chemistry oven the premise of the project is to have temperature increase with time exp(0- 300C) over 20 hours the rates may vary also I need to have the ability to have 2 or more different settings exp( 0-300C) over 20 hours with (0-200)over 15 hours then (200 -300) over 5 hours without any need of interference by the user. I hope to hear from you asap and sry its 500 char.

The frequency varies from 200Khz to 1Mhz. (There is a table for the various signal pulses on the PDF files). The 8 pulses are to drive a PNP transistor! An image of a pulse we are looking to achieve. The signal in Yellow is the result we are looking for. I have other tasks as well!! Can you do it?

Here is what I need: Home the gripper open to a micro switch on power up and wait for run input. When the switch is pressed and not released, the motor should make the travel forward 800 steps and reverse 800 steps and stop while touching the home switch. The circuit should wait until I press again the "run" button to go forward to close the gripper and reverse again to home switch. I need it to travel a specific distance. I only need the .ino file for this.

The design should be ready for sending it to the printing company. Requirements: - PCB type header that you put on top of it. - 3X PWM 4 PIN connector on it with 5Volts. - 8X 3 PIN 5V FAN would be nice, but I am not sure what the max amount is. - - 5X 4 PIN connector with 12V if possible. - - 3X MicroFit 3.0 Female INPUT -

We are unable to get hold of the Mega 2560 pro mini due to the chip shortage. We have lots of standard arduino mega clones that i can use. The project is to make a PCB that will act as a sheild that will plug into our existing PCB with pin headers (designed for Pro Mini) on one side and on the other will accept a standard arduino mega. This will allow us to use a standard arduino mega in place of the pro mini without changing our whole design.
